Hot Oil Heater

Thermal Oil Heater | Thermic Fluid Heater | Hot Oil Boiler

A hot oil boiler is an industrial heating system that uses a special thermal fluid, or heat transfer oil, to transfer high-temperature heat to industrial processes. Also called a thermal oil heater, thermal fluid heater, it operates in a closed-loop system and can achieve much higher temperatures than steam boilers without the corresponding high pressure.

Layout: horizontal, vertical, portable
Capacity: 25kw to 14,000kw / 100,000kcal to 12,000,000Kcal
Temperature: max 350℃
Available Fuel: gas, lpg, diesel, hfo, coal, charcoal, wood, biomass, briquette, electric etc
Applied Industries: fryer, reactor, refinery, resin, egg tray, plastic, dyeing, asphalt, rubber, electroplating
